Development record

itd-183 fifth-round ruthless nits: outDirLabel is empty for the default run directory so a populated default directory would be refused with a blank name (reachable only on a run-id collision); flowKeyRe is unanchored and refuses an excluded key name inside a quoted scalar, and htmlTagRe strips an autolink so a heading followed by one refuses — both fail closed but the corpus's long quoted reason strings in flow mappings are one sentence away from the first; the 'an amp entity' case in the assembler test is assembled and then skipped before its assertion, a probe that tests nothing.
